IMPROVEMENT IN MACHINES FOR DRYING AND SCO URING SHEET METAL.

Specification forming part of Letters Patent No. 198,980, dated January8, 1878; application filed September 6, 1877. I

To all whom it may concern Be it known that I, ADELBERT vP. HINE, ofWolcottville, county of Litchfield, and State of Connecticut, haveinvented new and useful Improvements in Machines for Drying and ScouringSheet Metal, which improvements are fully set forth in the annexedspecification and in the accompanying drawing.

My invention is in the nature of an improve- -ment upon the machinepatented. July 21,

1868, by G. E. L. Holmes; and has for its object such an arrangement ofa portion of the cleaning-rollers of said machine as will tend verymaterially to increase the quantity of oblong box form. 1 2 3 4 5 aregear-wheels,

geared together, and running on studs attached to the side of body A, orto short shafts running in boxes attached to the under side of the body.I I

The said train of gear-wheels may be run by means of a pulley attachedto the hub which carries gear-wheel 1.

Lying across body A are four rollers, b b b b9, firmly fixed upon shaftsrunning through them, and said shafts are adjusted to run in boxes oneither side of body A.

D D are universal joints interposed in the portion of the shafts torollers 1) 11 between the ends of the rollers and the boxes on thepinion end of said shafts. f are pinions on the ends of the shafts torollers b b 1) b and they gear into and are run by gear-wheels 2 3 4 5.

E is a connecting-bar, attached by its ends to boxes (1 and d h and hare two catchsprings, arranged to hold boxes 01 and d down in place onbody A.

A disengaging-pedal, to be operated by the foot, may be arranged torelease catch springs or hooks h and h from their hold upon boxes (1 andd In these machines, as heretofore constructed, all the scouring-rollershave been arranged to run in boxes permanently attached to the body.

To aid in effectually cleaning the metal, said,

rollers are covered with thick felt, and the boxshaped body is partlyfilled with sawdust sufficiently, perhaps, to immerse the rollerstherein one-half of their diameter.

In passing the end of a long strip of thin metal through the machine,preparatory to drawing it through to clean it, it is passed over roller72 under roller b again over roller 12, and finally imder roller bwhence it is attached to a revolving roller at the end of the machine,by which the strip is drawn between the cleaning-rollers and wound intoa coil.

A long thin strip of metal cannot be quickly and conveniently handledand placed in the position between the rollers, as above de-..,

and consequent cost for scouring and clean- I ing; and consists inplacing in the shafts to rollers b and b the universal joints D D, andin so fitting the boxes 01 and 01 on the front end of the shafts to saidrollers b and b that they will retain their proper places thereonwithout being bolted to the body A. I then bolt each end ofconnecting-bar E to boxes (1 and 01 This maintains the rollers in aposition parallel to each other, and aids in giving a simultaneousupward and downward movement to the two rollers 11 and b, or one end ofthem, as will be hereinafter explained.

Catch-hooks h and h are arranged to snap over and catch onto the top ofboxes d and d, or onto connecting-bar E, for the purpose of holding downthe ends of rollers 12 and I).

The operation of the machine and my improvement thereto is as follows,viz: The machine is set in motion by means of a belt running upon thedriving-pulley heretofore men tioned. Aworkman presses his foot upon apedal, which releases the catch-hooks h h from boxes 01 and (P, and bymeans of a cord and weight, or a spring attached to connecting-bar E,the front ends of rollers b and b will be lifted up to the positionshown in Fig. 2, the universal joints D D, interposed in the shafts tosaid rollers, as hereinbefore stated, permitting the front ends of saidrollers to be so lifted while they are running, and while that portionof their shafts upon which are pinions f are retained in proper positionto be -run by the gear-wheels 2 and 4. This position of the rollers 11and 1) permits the workman to lay the end of a strip of metal, 70, whichis to be cleaned, directly upon the top of rollers b and b and now, bypressing down the ends of rollers b and b so they will be caught andretained by catch-hooks h and h, the strip of brass will be found in thesame position in the rollers as if it had been passed end first betweenthem, first over and then under the other. Thus it is obvious that byletting the two rollers b and b up out of the way the end of the metalstrip can be much more quickly put into position to be cleaned, and muchtime saved.

What I claim as my invention is- 1. In a machine for scouring sheetmetal, the combination of the rollers 1) b running in fixed boxes on thebodyA of the machine, the rollers b and 12 with the universal joints D Din the shafts thereof, movable boxes d d, and the body A, substantiallyas and for the purpose set forth.

2. The combination, in a machine for drying and scouring sheet metal, ofthe rollers 11 and b and their shafts, the universal joints D D, theconnecting-bar E, boxes (I and d, and the catch-springs 7 and h, wherebythe cleaning-rollers can be opened apart at one end on the line of theiraxes, and be returned and held in an operating position, and whereby thesheet metal can be placed between the rollers laterally instead ofendwise, substantially as and for the purpose set forth.
